This is a transparent cobalt bead with petal murrini and buttterfly murrini.
The bead was built in the flame, annealed, and then was put onto a flat lap to bring out the detail in the murrini. On the surface the colors melted a little bit too much. The diamond disc took that off, and revealed the detail beneath.
The bead is washed well, and flame polished for a nice finish.
